The pom pom heart shape is just like the candy hearts. It's flat on the front and back. I found you can get a better shape if the front and back is flat opposed to rounded. Hope that make sense and helps. :)

Just wanna say that this instruction for the heart-shaped pom-pom was the best instruction for any craft project I have ever seen! THANK YOU VERY MUCH and I sure hope there will be more craft projects in the future.
